I wouldn't even want to try doing an album in a month, unless that's all i did for 30 days. Even then I can't imagine, unless I already had a bunch of rough pieces to simply record and master in a months time.
The only way I could see doing this, is if you had a group to collaborate and a professional 10 day session in a great recording studio with pros to mix and master, I could see coming up with 12 songs or so in a month. I've done something like that many years ago, like singing with a guitar, but they were never recorded and made into a cd.
The rules are fairly simple. Some of the projects I have heard from this are not so good. Certainly not polished anywhere near what you hear in this forum.
